城市地学环境研究主要涉及城市及其周边地区的地质和地理环境、地壳和地表运动、水环境、大气环境等方面及其相应的灾害潜在性的研究、防护，其中也包括了人类活动对地学环境的影响，其范围和深度主要取决于在人类活动中，直接和间接移动地球物质的量。文章强调了在城市，特别是在特大城市的持续发展中，要采取积极措施，预防和减少城市对抗地学灾害的脆弱性，同时阐述了对城市地学环境保护和管理的重要意义。

Urban geo-environment mainly concerns those regards in and around a city, such as the movement of earth crust and earth surface, conditions of hydrology, geology, geography and meteorology. The relevant studies on geo-disaster reduction and the influences resulted from human activities on the geo-environment are included as well. It is stressed in the paper that geo-environmental protection and management, as well as mitigation of the vulnerability of big cities again the geo-disaster are of significance to the sustainable development for Chinese cities.
